CAUTION: danger of loss of the afxed ATEX or IECEX marking.
It is forbidden to use the pump with temperatures higher than those allowed and specied in the manual; if
exceeded, conformity with the afxed ATEX or IECEX marking is cancelled.
If the pump is equipped with a STROKE COUNTER (to detect and/or view the number of pump cycles), provide
for the electrical connection.
Always protect the pump from possible accidental blows and from contact with incompatible uids that can dam-
age it and/or react upon contact with it.
If used for pumping ammable, aggressive, toxic or harmful uids for health and/or in installations in zone 1 - zone
21 - zone M2 and for pumping ammable uids (allowed by the marking), it is necessary to install an
adequate protection on the pump (for containment, collection and outow of the product in a safe area),
and a buzzer in case of spillage.
CAUTION: danger of pollution, contamination, injuries or, in extreme cases, death.
It is forbidden to install the pump in the absence of a suitable protection for containment with a collection
tank and outow in a safe area of ammable, aggressive or toxic liquids or with liquids that may represent
a health hazard.
The pneumatic circuit connection and the pump installation are thus completed.
4.5 CHECKS PRIOR TO COMMISSIONING
Depending on the type of application, the type of uid used, the installation/work environment, it is neces-
sary to afx appropriate indications and indicate the residual risk present near the pump.
Before commissioning the pump, in order to verify that the installation actually meets the intended oper-
ating conditions, it is essential to carry out the following checks with the pump running:
With a pressure gauge positioned directly on the air inlet of the pump (downstream of all devices and ttings
installed on the supply line), check that the detected pressure does not have any pressure drops com-
pared to the reading on the pressure gauge of the lter of the pneumatic network supply line.
With a pressure gauge directly on the delivery manifold of the pump, check that the actual pressure of the pumped
uid at the pump outlet is correct compared to the Technical data of the installed Model.
The pump is ready for commissioning.
